ABSTRACT A method of preparing improved coal-humus-based treatment and processing media from non-platy clayey coal material having a wide carbon nitrogen ratio of at least 10. Selected coal material is crushed, screened and subjected to at least one cycle of wetting and drying and then is thoroughly leached. Said coal material is then recrushed and screened to produce therefrom a quantity of fine particulate coal material having a maximum sizing passing through a 200 mesh screen, and a larger size coal material having a maximum diameter approximating 3/4 of an inch. Selected organic matter is ground and screened to produce fine particulate organic matter therefrom. In the first embodiment of the present invention a nitrogen-producing manure is formulated by intermixing said fine particulate coal medium with said fine particulate organic matter in a proportion of at least 50% of said fine particulate coal material. Said mixture being applied as an intermix with said poor soil, or as a surface application to said soil after seeding. In the second embodiment of the present invention said larger size coal material is used to remove pollutants from both domestic and industrial type polluted wastewater within the same treatment bed by a new type of composting and tertiary-treatment process wherein atmospheric nitrogen is produced as a by product of said process. In the third embodiment of the present invention said larger size coal- humus media is further processed by subjecting said media to hot water or boiling water leaching, and said fine particulate coal media are further subjected to said hot water or boiling water leaching and further wet re-grinding by explosion proof methods.
